I got to pet two tigers in Thailand and lie on one as well.One of them was walking around so they weren't drugged up or anything.

Later found out that in less than a year there were three terrible mauling's of tourists and that the 'zoo' was technically licensed as a 'restaurant' (they did have some tables...) But at least the outnumbered wardens had canes to keep the seven adult tigers at bay if needed!
